If you are searching something, and want to filter the results, would you rather have text boxes to get exact ranges you want, or a drop down set ranges, that are quick and easy to select.
So the drop downs might have price, under $100, under $200, under $500, under $1000, etc, where as for the text boxes you could have prices between e.g. $33 and $76. More specific, but really people would only want a maximum price anyway most likely.
What is better?
